Problem 1 – Service bandwidth upgrade
There is a need to model the impact of upgrading the service bandwidth bandwidth, the service take rate and the service mix on the access network.
For a given market, the access network planners want to perform Bandwidth Upgrade Scenarios, Uptake Growth Scenarios, and Service Mix Scenarios
The access network planners have to dimension the required capacity of the access nodes, to optimize the access network and to calculate related costs to upgrade it.

Problem 2 – Selection of Access Technology
Aim is to investigate the techno-economical impact of various access technologies on the network for a given market
Multiple techno-economical studies are carrier out for the purpose to determine the optimum access technology for the network
Selection is done by comparison of the economical parameters for each access technology
